WINDOW SCREEN OPERATOR Filed Dec. 13, 1930 Patented Jan. 12, 1932 PATENT OFFICE ALBERT INDECK, OF CHICAGO, ILLINOIS WINDOW SCREEN' OPERATOR Application led December 13, 1930. Serial No. 502,046.

This invention relates to screens and more particularly to window screens, although certain featuresthereof may be employed with equal advantage for other purposes.

5 It contemplates more especially the provision of built-in screens for automatic concealment and exposure operable responsive to Lwind-ow displacement, thereby precluding re- -moval or attachment during the different seao sons of the year.

yNumerous types of roll screens have liereto for been proposed but these have not proven especially advantageous owing to the intricate character of the operating devices. It

3 is manifest that simplicity ofconstruction and dependable operation thereof must be attended with* minimum wear of the moving ele- One object of the present invention is to simplify the construction and" improve the operation of devices of the character mentioned.

i Another object is to provi-de roll screens 'for permanent attachment to windows so as to accomplish the dependable operation thereof responsive thereto with minimum Wear.

Still' another object is to provide simple, Vdependable. and inexpensive operating means for built-in window roll screens.

A further object is to provide a novel and durable window screen operating mechanism. A still vfurther object is to provide novel means for effecting window screen operation vwithout resort to expensive or intricate instrumentalities.

Y Still a further object is to provide window `screen operating means of simple vand dev pendable construction for synchronized operation with window displacement.

Other vobjects and advantages will appear from the following vdescription of an illustrated embodiment of the present invention.

kserve as a closure therefor in accordance with modern and standard practice.

The window frame 1() is provided with side and end housings 17 and 18, respectively, and these are completely enclosed by pro erly shaped and sized board sidings 19 nailed or otherwise joined in any suitable manner 75 as commercial practice may dictate. End stiles 20 enclose the housing 18 to serve as a stop for the Window sashes 12 and 13 in their eXtreme closed positions, thereby shielding the opening defined by the frame 10 against a0 the elements. The usual sill 21 is provided immediately above the lower end housing 18, thereby approximating the structure of the standard window frame in every visual respect. Suitable counter-weights for the -85 sashes 12' and 13 may be provided or these may be dispensed with to meet any particular situation or desired condition of opera-- tion.

In order to provide summer closures for no the openings defined by the frame 10 responsive to the displacement of the sashes 12 and 13 from their normally closed positions, intermeshed wire strands defining flexible screens 22 and 23 are attached in any suitable o5 manner to the sashes 12 and 13, respectively, for operation responsive to the displacement thereof from their normally closed position, thereby serving as closures for the openings created in consequence thereof. The Screens 1,99

cla

22 and 23 are anchored to cylindrical rollers 24 and 25 journalled in suitable brackets 26 disposed interiorly of the housing 18 for attachment to the end stiles 20. In consequence thereof, the rollers 24 and 25 are completely concealed from view for rotary movement around a transverse axis in parallelism With the edges of the sashes 12 and 13.

As shovvn, the screens 22 and 23 are Wound around the rolls 24 and 25, respectively, for attachment along an edg-e thereof by means of any suitable fasteners. The other edges 29 of the screens 22 and 23 are lodged Within transverse grooves 30 provided in the corre,-

Aspending loW-er and upper edges 31 of the Window sashes 12 and 13, they being an- `chored therein by any suitable fasteners 32.

Horizontally disposed bars 33 arey seated Within the Windowv sash grooves 30 in adjacent contact With the screen edges 29 for at- Vtachment by means of the fasteners 32 there'- of. VThe bars 33 have lateral extensions 34 vWhich. project .Within the side housing 17 through the stile slots 35, and the screens 22 and 23 also extend laterally for disposition vvithinthe stile slots 35, thereby completely closing the opening defined by the displaced Window sashes 12 and 13 lto preclude the entrance of flies and foreign substances nevalent in the atmosphere.

In order to operate the screens 22v and 23 responsive Yto the displacement of the Window sashes 12 and 13, aligned sprockets 36, in this instance four, are Vattached to the extremities of the rollers 24-and 25 beyond the brackets 26 for confinement in the side housings 17,

the sprockets 36 on the respective rollers be- 4ing'in vertical `alignment for mesh with flexible chain members 37. As shown, the chain members 37 mesh with the teeth of the sprockets 36, and the diametral meshing eny gagement thereof is substantially equal to the diameter of the rollers 24 and 25 With the Without any strains or stresses thereon responsive to the corresponding displacement vof the Window sashes 12 and 13. This operation is enabled owing to the fact that the "linear movement of the screensl 22 and is `substantially the vsame through the ylengt-l thereof with the synchronized or corresponding displacement of the Window sashes 12 and 13. This is accomplished by virtue of the diametral equivalency between the sprockj sashes 12-13.

ets 36 and rollers 24+25 so that corresponding operation effected responsive to manipulating one or the other of the Window Itis ossible to provide flexible metallic strips o9 as interposed members connecting the chains 37 to constitute anendless member tensloned about the aligned sprockets 36 in each of the side housings 17. The extent of the stile slots 35 serves as a limit for the Window and screen displacement in that contact with the bar extremities 34 serves as Va stop therefor. It is to be noted that this arrangement affords very simple, inexpensive and dependable operating instrumentalities, and that the Window sashes 12 and 13 may be synchronized for corresponding displacement in opposite directions, or these may be independently operated by resort to idler sprockets vor pulleys' in an obvious manner vWithout departing from the spirit of the invention. l

Various changes may be made in the embodiment of the invention herein specifically described Without departing from or sacril licing any of the advantages of the invention as defined in the appended claims.
